Big Data

Big data comprises of large volume of datasets which is very difficult to manage within the traditional computer. The big data includes huge volume, high velocity and extended variety of data.

Hadoop is an open source framework written in java which is used to manage the large volume of datasets by the clusters of computers using the mapreduce concept. Hadoop MapReduce is a software framework in which the map collects the large input of data and converts into the sets of data whereas the reduction of these datasets are performed after the map process.

HDFS

The most common file system used in the hadoop is Hadoop Distributed File System(HDFS) and it follows the master/slave technique. HDFS is a fault-tolerant and performs the parallel processing. It is designed by using the low cost hardware. It stores the metadata and the application data separately. The meta data is stored on the dedicated server called Namenode which contains the file system. The application data is stored on the other server called the Datanodes which contains the actual data. All these servers are communicate with each other using the TCP based protocols.

Hbase

Hbase is the column based distributed database management system in which the data is stored in the form of columns in the tables whereas the traditional RDBMS stores the data in the form of rows. It provides the random quick access to the huge volume of data compared to the HDFS and real time read/write access to the big data. It stores the result in the form of hash tables.

What is Cloud Sim?

     CloudSim is a Simulation Tool or framework for implementing the Cloud Computing Environment. The CloudSim toolkit enables the simulation and experimentation of Cloud Computing systems. CloudSim library written in java, contains classes for creating the components such as  Datacenters, Hosts, Virtual Machines, applications, users etc.

     These components are used to simulate the new strategies in Cloud Computing domain. These components can be used to implement the various Scheduling Algorithms, Allocation Policies and Load Balancing Techniques. With the simulation results we can evaluate the efficiency of the newly implemented policies or strategies in Cloud environment. The CloudSim basic classes can be extended and one can add new scenarios for utilization. CloudSim requires that one should write a Java program using its components to compose the desired scenario.

The basic components in Cloudsim which will create the Cloud computing environment are:

1. Datacenter :    Datacenter, first component should be created, with an VmAllocation policy. The Hosts, and VMs are created inside the Datacenter only. The resource provisioning is performed based on the allocation policies.

2. DatacenterBroker :    A broker, communicates between the user and the datacenter. The  VM and Cloudlet requests given by the user are submitted to broker. The Broker will send the requests to datacenter. And also collects the result from the datacenter and sends it to the user.

3. Host:    The Host class is used to simulate a physical machine. It manages the VMs allocated in it.

4. Vm:    The Vm class is used to simulate the Virtual Machine which runs inside the Host and executes the applications or tasks.

5. Cloudlet:    The applications or tasks to be executed in Vm are simulated using Cloudlet class. The Class contains the basic application characteristics and runs inside the Vm.

6. VmAllocationPolicySimple:    It is the policy defined for allocating the Host for each Vm in the datacenter.

7. VmScheduler and CloudletScheduler :   It is the scheduling policy that defines the scheduling order of Vms and Cloudlets respectively.
